A pipe section 31 is threaded upwardly through theblock 8 and within which the tubular'member 28 is received as clearlyshown, while an elbow 32 joins the. lower end of the vertical pipe. 31to the. horizontal pipe 33. A \viek 34 ot'any desired form is positionedin the pipe 353 and the oil or other burning tluid fed from the cvlinder 25 passes dmvnwardly through the tubular member 28 to beabsorbed by'thc wick 3i.

The burner is mounted in a protective casing consisting of asubstantially reversed L-shaped member 35 having the lower front wallthereof turned upwardly as at 36 to provide a lip so that the materialcontained within the casing and surrounding the burner pipes will beprevented from falling out. It is preferably desired to till the burnerpipe casing with clay, sand or similar material so that the flame fromthe wicks 3 will not be blown baekwardly into the casing by the fanwheel 16.

The platform 9 carries an. operators seat 37 while'therear end of theframe. bars 5 are supported upon rollers 38 mounted in arms 39 that arefixed to the horizontal shaft 42 jonrnaled in the bearings 41 upon theplatform 9. A crank handle. 42 is fixed to'the. shaft and carries atensioned locking nod 43 adapted for engagement with the segment ru'ck44 so 'that by shifting the crank handle 42 rearwardly from thepositl'on shown m Fig. 1, the supporting arms 2 39 of the rear wheels 38will be moved to a substantially vertical position and elevate the rearend of theframe so as to regulate the distance between the burner andthe ground. In order to prevent side air drafts from interfering withthe usual operation of the burners, there are provided side wind shields45 supported as by bolts 46 to the side bars 5 of the frame with thelower edges thereof extendingslightly below the burner as is indicatedin Fig. 1

By the forward propulsion of the machine, the land roller 10 is drivenin the direction as indicated by the arrow in Fig. 1 which communicationis tra-nsn'iitted to the fan blower 16 by the sprocket and gearconnection above described so' that the fan blower will be rotated inthe direction as in- .dicated by the arrow. The. air is blown downwardlyupon the. ground by the. particular disposition of the blades 17 and theflame from the wick 34 is accordingly down wardly directed into directcontact with stalks, weeds or other rubbish to be burned.

the land roller 16, it is to be understood that the device may bereadily applied to the present construction of land roller by the simpleaddition of a sprocket gear upon the land roller bearing and theoperation thereof will be identical.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that various forms, modifications and arrangements of theparts may be made without departing from the spirit and scope of theinvention as claimed.

What I claim as new is:

l. A machine of the class described comprising a supporting frame, aburner carried thereby, means for supplying fuel to the burner, meansfor directing the flame of the burner downwardly, and a land roller riedthereby, means forsupplymg fuel to the burner, means for raising andlowering the frame to vary the position of the burner relative to theground, means for directing the flame of the burner downwardly and aland roller positioned forwardly of the burner adapted to operate thelastnamed means.

3. A machine/of the class described comprising a supporting frame, aburner carried thereby, means for feeding, fuel to the burner, means fordirecting the flame of the burner downwardly, a land roller forsupporting, the forward end of the frame constituting driving means forthe flame directing means, and means positioned at the rear end of theframe for raising and lowering the. frame to vary the distance betweenthe' burner and ground.

4. A machine of the class described comprising a frame, a burner carriedthereby,
